I work for a law firm and we are starting to routinely set up shop in hotels for trials. What I thought I could do was create a mini LAN in the hotel conference room consisting of a switch with several laptops, a server, and a local network printer connected and use the laptop's dual network cards to connect to the Internet and the local network at the same time.
I have the local mini LAN configured with 10.10.10.x, 255.255.255.0, no gateway addressing which the server acts as DHCP for this range. I plug the wire into the switch giving the laptop's NIC a 10.10.10.x address. Then I use the laptops wireless NIC to get on the hotels Internet connection.
All works well. I can access both the Internet and print until I connect to VPN. Once connected, we use Cisco's web based AnyConnect, the VPN gets 192.168.200.x, 255.255.255.0, 192.168.200.1 addressing but I am unable to connect to my 10.10.10.x LAN at all. I can even ping the printer. I am assume that traffic is trying to go through my VPN and finds a dead end. VPN works great. I can access my corp LAN fine, ping servers, etc...
Surely I'm just missing some sort of routing here. Is there anything I can do?
